It works fine *except* for one issue - from the extended position it needs a push to retract! Once I have pushed down on it gently it retracts without any issues.

I installed a type 04 mast which needed the nylon cable to be cut so it would fully retract - apparently the longer nylon cable is for the 6000EL antenna. I've tried to adjust the clutch nut to no avail

My theory is that the nylon cable is either too long or too short but I'm too scared to cut any more of the nylon cable to see if it fixes the strange behaviour.

The clutch is spring loaded so it should be fine. Three thoughts come to mind

1. Did the replacement cable have "teeth" rather than was solid. Should be solid
2: Did you lubricate the white cable (or has lubricant made its way to the clutch. It may be slipping as a result.
3: Did you slightly warp the telescopic antenna before installing, meaning its catching slightly. That said, have you lubricated the telescopic bit ?

I very much doubt cutting the cable length will alter this as all that means is the aerial doesn't extend as completely.

The replacement cable has teeth, but according to the vendor (Soundlabs Group) this is perfectly fine. They don't stock the type 02 mast for these units anymore as they are NLA. I was told that replacing with the type 4 mast was fine but I'd need to cut down the cable to make it fit in my 6000U.

I did not lubricate the nylon cable but it is very possible some lubricant made it into the clutch from when I cleaned the unit. However I don't think this is the issue. What I have noticed is that when I turn off my radio, I hear a 'click' but the motor does not move. When I push down on the mast it *does* move and retract the mast as intended.

The telescopic bit has been lubricated and it freely extends and retracts when it's been removed from the car.

This weekend I'll have a further fiddle, hooking it up to a 12v battery with the whole unit removed from the car. Provided I have time left over after working on my new w124 project!
